LIQUID-DISPENSING DEVICE.

Application filed March 15, 1926. Serial No. 94,943.

This invention provides an article combining a brush and a fount in-a single organization, whereby the brush may be charged with material with-out requiring a separate holder therefor;

The invention is particularly adapted for tooth and shaving brushes, the handle constituting a reservoir for receiving the dentifrice or the saponaceous agent according to the adaptation of the invention for cleaning the teeth or lathering theface. v

WVhile the drawings illustrate a preferred embodiment of the invention it is to be run d'erstood that in'adapt-ing the means to meet specific needs and requirements, the design may be varied and such other changes in the minor details'of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the drawings hereto attached in which, I

Corresponding and like partsare referred to in the following description'and designated in the several views of the drawings by like reference characters. 1 U

The device. comprises a handle l'which is hollow to provide a reservoir for receiving the dentifrice, saponaceous agent or other material to be dispensed. The handle 1 is closed at one end by means of a cap 2, and a plug'3 is fitted to the opposite end and con stitutes a closure therefor as well as supporting means for the brush, whether of a convent onal type for cleaning the teeth, or of the form for, lathering the face. The numeral4 designates a tooth-brush, in the back of which is formed a passage 5. The passage 5 terminates a short distance from the inner end of the brush and an opening 6 leads fromvthe inner or forward end of the passage 5' to supply the dentifrice to the bristles 7 or body of the brush. A tube 8 connects at its delivery end .with the passage 5 and obtains a snug fit in the plug 3. The tube 8 has a lateral feed opening 9 adjacent the inner side of the plug 3' and the mate rial passes from the handlel through the opening 9 and into the tube 8 to be dispensed by .the brush. The dispensing tube 8 is fixed and extends within the handle 1 some distance and has openings 10 and 11 at different points in its length for a purpose to be explained hereinafter. A guide tube 12 is fixedly supported within the handle1; and receives a plunger and the inner portion ofthe dispensing tube 8. A plug 113 closes the rear end of t-he'guide tube 12 and forms an abutment for a coilspring 14 which is located'within the rear portion of the guide tube 12 and normally tends to hold the plunger at its forward position. The plunger comprises a head 15 and spaced -conce'ntric portions 16 and 17, the portion 16 being tubular and slidable on the inner .or rear end of the dispensing tube 8. The

part 17 projects beyond the part 16 and is slidable withinthe dispensing tube 8 and is "provided with a passage 18 from which openings 19 and 20 extend to register with the openings 11 and 10 of the dispensing tube j 8 when the plunger is moved rearwardlyto the limit of its throw, as indicated .most clearly. in Figure 4. An opening 21 is formed in a 'side of the tubular part 16 and registers with the opening 11 of the dispensing tube 8 whenthe plunger is in the position shown in Figure 4. An opening 22 formed in aside of the guide tube 12 in line with the opening 11 registers with said opening and the opening ,21 when the plung er is moved rearward. Figure 4.

A support 28 is secured within the handle with the opening 22 of the guide tube 12.

An opening 27 formed in a side of the handle 1 is positioned to communicate with the passage 26. A slot 28 formed in a side of the handle 1 in register with the slot 24; receives the outer end of the pin 25, a slot 29 formed in a side of the guide tube 12 in position to h register'with the slot 2st of the support 23 receives the inner end of the pin 25. A support 30 secured within the handle 1 receives the forward end of the guide tube 12 which may be connected thereto in any preferred way.

In the modification shown in Figures 8 and 9, the back of the tooth brush is of sectional formation and comprises the section 31 to which the bristles 7 are attached and the section 32 which is fitted in a recess formed in the top of the section 31. The passage 5 and opening 6 are formed in the section 32 and the dispensing tube 8 extends into the section 32 and is in communication with the passage 5. The section 32 may form a part of the plug 3 and has a projection 33 at its forward end to enter a socket at the forward end of the recess of the section 31. The section 31 is detachable from the section 32 and is provided at its rear end with a projection 34 to enter an opening formed in the rear end of the section 32 adjacent the handle 1.

The handle 1 constituting the reservoir is adapted to be supplied with the dentifrice, saponaceous agent or other material by removing the cap 2 and after the handle has been charged the cap 2 is replaced. The interior parts normally occupy the position shown most clearly in Figure 3, wherein the several openings or ports are out of register, thereby preventing any discharge of the material from the reservoir. To supply the brush, the plunger is moved rearward by engaging a digit of the hand with the projecting end of the pin 25 and moving the same to the rear end of the slot 28, as indicated most clearly in Figure l. The article is held in upright position to insure an outflow of the material from the handle to the brush. lVhen the plunger occupies the position indicated in Figure 4, the spring 14: is compressed and the several openings or ports register so that air enters the opening 27 and passes to the interior of the handle through the openings 26, 22, 21, 11, 19, 18, 20 and 10. At the same time the material from the reservoir of the handle flows through the opening 9, tube 8, passage 5 and opening 6 to the brush. After the brush has received the required amount of material the pin 25 is released and the spring 14 moves the plunger forwardly to the position indicated in Figure 3, thereby throwing the several openings or ports out of register and cutting off the discharge of the material. The portion 17 of the plunger in which the passage 18 is formed constitutes in effect an air supplying tube, since the air flows therethrough from the outside to prevent the formation of a vacuum inthe reservoir when the plunger is adjusted to effect a feed of the material from the reservoir to the brush. The part '17, by reason of its function,'con stitutes an air supplying tube and since its forward end is closed or solid and obtains a snug fit within the dispensing tube 8 it also operates as a plunger to positively eject the material should the same be of a viscid nature or tend not to flow readily through the dispensing tube 8 to the brush.

Having thus described the invention, I claim: 7
